Google Technical Support Engineer interview questions

Fully online, it was the messiest and the longest interview process ever. It took over 10 weeks for the final decision and 7 meetings. The first two meeting were with a recruiter who conducted a quick screening and on the next meeting explained the recruitment process and interviews order. First interview (3rd meeting) was with a hiring manager who was asking mainly behavioral questions. That went well. The second interview (4th meeting) was a technical one, during the first half I was being asked about linux, that went well too and during the second half the engineering guy said: "I can see you have chosen Java for  your programming skills evaluation." Nothing in my resume says anything about Java, I provided my language preferences but the recruiter wasnt prepared for it so he started making up random questions , he became nervous and so did I. The third interview (5th meeting) was db related. It was actually interesting sparring because I was providing answers in a technical context that my recruiter wasn't very familiar. A couple questions were related about tech I didn't know (and not included in cv). The 4th interview (6th meeting) supposed to be about googliness but to my surprise it was another technical interview, mix of db, os questions. It went well. I had to wait couple weeks to get a feedback response and the feedback was... 'a hiring committee  is not ready to provide a feedback' :). I was once again asked  to participate in another interview. The 5th interview and the last one (7th meeting) was actually lost and found googliness with a support lead. It was again kinda behavioral/scenario/situational, the interviewer was friendly, I think it was a really good meeting. Couple weeks of silence again.  I emailed my recruiter twice,  asking for a decision. I got the reply back that they are still very interested in my profile and they are setting up a meeting a site lead to introduce me. Then two weeks later a reject mail came.
